请帮忙分析一下effect 和affect ；supply 和 provide的区别多谢！！

affect和effect二者的区别在于:

affect: 以被影响的事物做宾语.
effect: 以"改进","变化"等类的词做宾语.

例如:

Rreading in bed has affected his eye-sight.(在床上读书,使他的视力受到影响)

By giving him the electric-shock treatment, the doctor has effected a partial cure of his short-sightedness.(通过电流刺激疗法,医生部分地治疗好了他的近视)

My opinion was affected by the recent development of events.(我的看法受到了最近事态发展的影响)

The recetn development of events effected a change in my opinion.(最近事态的发展,使我的看法发生了变化)

从以上两组例子可以看出,affect 着重"影响"的动作, effect着重"造成"一种特殊的效果
另外, affect在做"影响"解释时,它的"影响"分三种.
1.使之更动,起变化,没有好与坏的意思,客观的.
2.对,,,,发生不良影响
3.感动

例如:

Does the change affect your plans(更改影响了你的计划吗?)

Do you think the crops will be affected by the protracted rainy season(你以为雨季这么长,不会对农作物产生影响吗?)

I was deeply affected by this book(这本书使我深受感动)
